I've fitted a bigger turbo to my t-jet and a forge actuator but have a strange noise.

it sounds like air rattling passed something loose when the wastegate opens. is this right? its more so when you first get in the car ( cars cold ) from listen on you tube its not turbo chatter. It happens after you've had your big bit of boost from the turbo. any ideas. and anybody know the safest highest working pressure of a mito 155 turbo. dont want to over adjust my actuactor.

atm I got a 13 - 23 PSI spring in my actuactor and left the arm the same length as the standard actuator

Can you upload a vid or sound clip? not for me but for those that know.

you sure it not just the wastegate noise mate if its after boost

it probably is, and just me paranoid.

I will upload a video asap.

its a good chance my actuator wants adjusting because my actuator it set just above standard boost on the t-jet but I now have bigger turbo.
